Nice Myres rigs are still out there. I found this one on ebay for a very reasonable price last year. Shown with a 4" 3rd Model 44 HE.

Where/who did you get this rig from?
American Classic Gunleather is who you want. You can find him on facebook. Great quality and excellent turn around time.
Simply Rugged makes good holsters at decent prices. I think they make one like you described.
I look for left hand Hunter western belts on Ebay because I think their belts with hardly any drop at the loop are ideal for what you describe. I've done that myself in the past. Alfonso and Bianchi both made SA fast draw rigs with the holsters through the slot like that.I like western drop loop belts. But instead of hanging holster from the slot I put over top of belt and bring it back through the slot. Of coarse this only will work with hostess that have snap or buckle strap that is connected to belt loop. Gives wide skirt to comfortably carry the weight will keeping gun up high. I don't like western rigs flopping around. I have modified a bunch of holsters to ride this way.
They even make them for the 5" L-frame. I just ordered one for my 986.
